a The B-1B bomber is no longer nuclear. It was officially
removed from the SIOP in 1997, but retained in a Nuclear Rerole Plan until March 2003, when the Office of the Secretary of
Defense directed the Air Force to discontinue the plan. The B-1B is no longer
nuclear-capable.b The first Borey-class SSBN was launched in 2006 and might
be entering operations in 2008 with the Bulava SLBM. A total of six Borey SSBNs
are planned. Delta IVs are being upgraded to the modified SS-N-23 (Sineva). All but three of the original six Typhoon-class SSBNs have
been retired. One has been converted to test launch platform for the SS-N-30
(Bulava) SLCM. The Borey will probably replaced Delta IIIs on a one-for-one basis. c The Pentagon
declared in May 2007 that the DF-31 had achieved "initial threat capability"
in 2006. d The first Jin-class (Type 094) was launched in 2004 and
first spotted with commercial satellite images in July 2007. A second
Jin-class SSBN has
been launched and a third appears to be under construction. U.S. naval
intelligence has
projected that China might build five SSBNs if it wants to have a more
permanent sea-based deterrent, and the DOD 2008 DOD report in March 2008 that Chinese forces by 2010 might include "up to five" Jin-class SSBNs. e The DOD reported in 2008 that 50-250 DH-10 have been deployed in air- and ground-based versions. Only a portion of the H-6 force, perhaps 30 aircraft,
are estimated to have secondary nuclear mission. The H-6 is being modified to carry the DH-10. The Q-5 may no longer be nuclear-capable. There is no
reliable information that newer tactical aircraft have been assigned nuclear
role.
